In general the grade of the polynomial in the numerator should be less than the grade of the polynomial in the denominator.
If it's not presented in that way, you should divide the numerator polynomial by the denominator and express it that way.
No tricks this way.
I was going back over this question and i wanted to express in partial fractions having expressed quite worried actually as i could do it first time round by putting as you would expect. At this stage however I can only get 1=4B+4D. I previously got B=1/8=D and as i said i cant get these this time round so if anyone could show me this would be great!
I think you've made a mistake,
I haven't worked through it further, I'd need to pull out my notes from last semester. If you have more trouble I'll see if I can remember what to do. Those are pi in the exponent by the way, they are so small on my screen they almost look like x.
lol apologies that is an entirely different question which I understand the principles of now. Yes you are right i missed the x. the question was express which i did by completing the square(matching coefficients didnt seem to work!) so I get the answer then it says hence express in partial fractions(this is where i get stuck) i do = the answer is what i said in my other post with root 3 on the denominator but i cant figure from this point on wards how i did this a long time ago,,,i can only get 4B+4D=1 putting in x=0 any suggestions??? regards
